Вплив хелатних сполук (метіонатів) на м’ясні якості та ветеринарно-санітарні показники яловичини

Abstract

Providing the population with food and, first of all, meat is one of the main prerequisites for the development of Ukraine. Biologically complete and relatively inexpensive beef can only be obtained from animals of the meat production direction. One of the conditions for obtaining high-quality products is the full feeding of animals, which allows them to realize the genetic potential laid in the breed. At the same time, the problem of balancing rations for a microelement nutrition, which is characterized by a shortage in soil and feeds of macro- and microelements, becomes important. Some of these elements are components of biologically active compounds and regulators of various metabolic processes, and their lack or excess can lead to significant metabolic disorders in the animal's body and loss of productivity.Despite numerous studies devoted to the study of metabolism and individual parts of antioxidant protection of animals, work revealing the physiological and biochemical mechanisms of these processes in cattle for the influence of scarce microelements is quite limited. The issues not only of protein metabolism and the antioxidant defense system in the age aspect remain, but also the course of these processes for the correction of mineral nutrition, which predetermined the choice of the direction of research, the purpose and objectives of this work.The imbalance in the diet of cattle fattening on mineral substances is accompanied by a violation of metabolism, reduced productivity and resistance of animals, deterioration of the indicators of veterinary and sanitary examination and meat quality. Ratios of cattle, which include feeds require the mandatory enrichment of their iron. Feeding iron metionates positively affects the physiological state of the organism, increases the number of red blood cells, hemoglobin.When using iron in the form of chelates, a high coefficient of its assimilation is established. In blood, the serum iron content of iron increased and this contributed to a decrease in total and latent iron binding capacity of serum. Iron chelates (metionates) more intensively stimulate protein synthesizing function, which manifests itself by increasing the content of total protein, albumin and reducing the amount of globulins.Application of micronutrients and their chelate compounds (metionates) and other biologically active substances has its advantages, the level of assimilation of heavy metals, radionuclides from contaminated feeds and water is reduced, chelate complexes of trace elements (МЕ) easily penetrate through cell membranes, allowing to carry out purposeful influence on exchange substances and energy and to correct the deficit of ME in the relevant biogeochemical zones.
